Changing the Guard at Buckingham Palace takes places at 11.30am each day and has become a popular tourist attraction.

Just last week another tourist was subject to the power of the Queen's Guard while absentmindedly strolling through one of London's parks.

The guardsmen were on the move outside London's Buckingham Palace when the tourist was barged out of the way.

According to the Mail Online, the tourist in question was Gerry Weatherhead, a retired RAF engineer.

He said: "As a former military man myself I'm more embarrassed than anything else - but no one was hurt and there was no harm done. It's quite funny really!"

The Guards were also forced into the spotlight in April when during the Changing the Guards ceremony one poor soldier lost his footing on a shiny metal plate on the floor.

The embarrassed soldier quickly scrambled to his feet and maintained his composure throughout but, unsurprisingly the video went viral almost immediately.

Meanwhile in September last year, a dancing guardsman put on an unusual show outside Buckingham Palace after breaking strict rules by performing ballet-style pirouettes in front of the royal residence.
